Maybe I suck at searching, but at what point does the LS7 clutch max out in a GTO?
Car is an 05 GTO. Weighed in at 3680 without the driver. Made 430whp, 390 torque. LS7 clutched held very well at this setup, but PRC Stg 2.5 heads are being added, and a FAST102 may be added as well. Its a DD/Street car, but will see the track for a few runs 1x a week for the summer.

At the new setup, would it be reasonable to assume that the LS7 clutch will continue to hold up? At what point, on a nearly-stock weight GTO, will the LS7 clutch be maxed out, and start to slip?

I think I read some guys running them with 500 rwhp.

I have 500rwhp and have launched with mt et streets bias and havent had a problem only 1 launch however. No clutch slippage on dyno run either. I myself am wondering how long it will last launching hard at 500rwhp

My only reservation is that the F-Body guys arent dragging as much weight as my GTO is.

if you are not slipping the LS7 clutch, you should be fine. IMHO

True.
I have to slip it to hook at the track tho. Im on Direzza Star Specs. haha.

I just dont have a ton of cash, but I also really dont wanna throw the car back together, and end up having to drop the xmission and have the car down again. It's supposed to be my DD

as long as you don't hot lap it and let the clutch cool down between runs it'll last a lot longer. it'll start to slip if you hot lap it and get stinky.

409rwhp/377rwtq. Held up fine with stock power for 30k miles, then when i started to do my cam/ longtubes a month later it slip on the upper end rpm

I'm at your power level with a lighter car and it's held up for 15,000 miles so far just fine. If you go to the track a lot and flog the launch, I would recommend an upgrade. I've smelled mine a couple of times with some back to back 5K launches. For spirited street driving, it's fine.

Add 1 more at 500 whp 500 ft-lb, have about 8k on mine with a few track passes with radials with no problem, but as stated they arn't reccomended for hot lapping.

You will be fine, but consider saving up for a better clutch man.
